Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, a water purification system for urban small watersheds, the system sequentially includes a water storage tank, a sedimentation tank, a purification tank and an artificial wetland according to the direction of water flow; the storage tank, the settlement tank and the purification tank are connected through pipelines.

[0039] A water retaining dam is set in the reservoir, and the water retaining dam is used to intercept the water body in a small watershed. The height of the water retaining dam is 0.5m above the bank of the water basin, and the bottom of the water retaining dam is provided with 3 groups of outlets. The water outlet and the water outlet are provided with a gate, and the gate is provided with a filter screen, and the filter screen is a cage structure (such as figure 2 ), the inside of the cage-like structure is also provided with 3 layers of filter screens. The cage-like filter screens are symmetrically installed o...

Abstract

The invention discloses anurban small watershed water body purification system and method, and relates to a river purification system.The urban small watershed water body purification system sequentially comprises a water reservoir, a sedimentation tank, a purification tank and an artificial wetland in the direction of water flow, wherein the water reservoir is used for storing water and filteringfloating or suspended solids; the sedimentation tank is mainly used for sinking hard-to-sink matters by a chemical method; a chemical flocculating agent is added into the sedimentation tank; the flocculation effect is obviously improved by reasonably controlling the type of the flocculating agent; a small amount of the flocculating agent is added, so that a good flocculation effect can be achieved; the purification tank is used for purifying a water body; the purified water body can be finally used for constructing the artificial wetland; and the water body can be better purified through thesystem, the purified water body can be used for improving landscape,the environment is improved and the life quality of people is improved.

Description

technical field [0001] The invention relates to a river purification system, in particular to a water purification system and method for urban small watersheds. Background technique [0002] Urban rivers are of great significance in urban ecological construction. Urban rivers provide water sources for urban life and production, reduce the urban heat island effect and flood disasters, and also have shipping, green space, and are part of the diversity of urban landscapes. With the rapid development of the economy and the rapid expansion of the population, the unrestrained discharge of domestic wastewater and industrial wastewater and the extensive use of chemical fertilizers have caused the ammonia nitrogen content in natural water bodies to be generally high, and excessive human interference has degraded the original natural water ecosystem. , river water pollution is increasing, the natural landscape of the river is destroyed, and the ecological regulation function of the ri...
